Work Experience

Linux System Administrator

Self-Built Home Lab

Jan 2022 - Present

Designed and built a multi-VM home lab from scratch — configured static IPs, inter-VM routing, DNS resolution, and network segmentation across RHEL/CentOS and Ubuntu nodes to replicate a real server environment. Enforced least-privilege across all systems — sudoers configuration, ACLs, SUID/SGID auditing — significantly reducing simulated attack surface and unauthorized privilege escalation paths. Administered 15+ services via systemctl (Apache, Nginx, SSH, cron, rsyslog, fail2ban) — diagnosed failures through journalctl log analysis and restored uptime with zero data loss across all test cycles. Locked down SSH on every system — root login disabled, key-only authentication, AllowUsers directive configured, fail2ban deployed — zero brute force successes in all simulated attack tests. Deployed 10+ Docker containers and Podman pods — authored Dockerfiles, configured volumes and bridge networking, orchestrated multi-container environments with docker-compose. Wrote 20+ Bash scripts for log parsing, health reporting, automated backups, and user provisioning — eliminated repetitive manual admin tasks and improved consistency across the lab. Provisioned and managed AWS infrastructure — EC2 instances, S3 bucket policies, IAM least-privilege roles with MFA, VPC with Security Groups — following AWS security best practices.
